Abstract

It is shown in the theory of finite Fermi systems that giant resonances can be considered as zero-sound excitations in concrete nuclei. Solutions to the zero-sound dispersion equation in symmetric nuclear matter, ωs(k), are obtained. Hydrodynamic models determine the wave vector k A corresponding to giant resonance in a nucleus with atomic number A. The real and imaginary parts of ωs(k A ) compare to the energy and escape width of giant resonance. Calculations are performed for giant dipole resonances.
